Thomas Bareiß

Since the 2021 elections, Bareiß has been serving as his parliamentary group's spokesperson for transport.

In spring of 2020, amid the first outbreak of the Covid-19 pandemic in Germany, Bareiß, who is known for his close relations with Azerbaijan, following a request from there, made a phone call to Löwenstein Medical from the Federal Ministry of Economics, the second largest federal government manufacturer of ventilators in Germany. According to reports in several German media outlets, during the conversation Bareiß "insisted in the telephone call that ventilators be delivered first to Baku and that this was due to the good economic relations between Germany and the Caucasus Republic." The news came at a time when a number of CDU/CSU MPs were implicated in corruption allegations related to face mask procurement during the pandemic and lobbying scandals related to "Azerbaijani Laundromat" and "Caviar diplomacy".

Bareiß rejects the introduction of a CO2 tax. He has justified this due to the allegedly high costs for broad sections of society being problematic. He is open to CO2 emissions trading. After the publication of the Rezo video The destruction of the CDU and the poor performance of the CDU in the 2019 European Parliament election, Bareiß criticized first-time voters and their demand for a CO2 tax. In a tweet, Bareiß wrote that when it comes to a CO2 tax "if first-time voters make their own money and feel for themselves who has to pay for everything" then "the choice may look different again". Climate activists, young influencers and the media criticized Bareiß for this statement. The parliamentary director of the parliamentary group of the left, Niema Movassat, accused Bareiß of being detached and arrogant in dealing with first-time voters. The CDU politician Ruprecht Polenz also classified Bareiß's tweet as a mistake.

With the formation of the fourth Grand Coalition under Merkel in 2018, it was announced that Bareiß would move to the position of Parliamentary State Secretary at the Federal Ministry of Economic Affairs and Energy under Minister Peter Altmaier. In this capacity, he also served as the Federal Government's Commissioner for Tourism (since 2018) and for small and medium-sized enterprises (2020–2021).

Ahead of the Christian Democrats' leadership election in 2018, Bareiß publicly endorsed Friedrich Merz to succeed Angela Merkel as the party's chair.

In June 2017, Bareiß voted against Germany's introduction of same-sex marriage.

On 27 January 2015, Bareiß voted against the Merkel government's proposal for a four-month extension of Greece's bailout; in doing so, he joined a record number of 29 dissenters from the CDU/CSU parliamentary group who expressed skepticism about whether the Greek government under Prime Minister Alexis Tsipras could be trusted to deliver on its reform pledges.

In August 2015, Bareiß and 72 other members of parliament were rated "poor" by the abgeordnetenwatch.de platform, because of not answering any questions from citizens on the platform. Bareiß justified this in a letter to the editor to the local press with a reference to the alleged lack of seriousness of the platform.

Amid a 2014 debate over whether Germany needs to rethink its energy strategy and reduce its dependence on Russian gas imports due to the Russo-Ukrainian War, Bareiß spoke out in favor of liquefied natural gas (LNG) imports and demanded an effective regulatory framework for a German LNG terminal.

In the negotiations to form a Grand Coalition of Chancellor Angela Merkel's Christian Democrats (CDU together with the Bavarian CSU) and the Social Democrats (SPD) following the 2013 federal elections, Bareiß was part of the CDU/CSU delegation in the working group on energy policy, led by Peter Altmaier and Hannelore Kraft. Following the 2016 elections in Germany's important state of Baden-Württemberg, he was again part of the negotiations on a coalition government, this time of the CDU and the Green Party under Minister-President Winfried Kretschmann.

In 2010, Bareiß worked to limit the growth in solar-panel installations in Germany as he saw the rising costs to consumers undermine the acceptance of alternative energy. In a letter to then-Environment Minister Norbert Röttgen, he demanded that the government cut the guaranteed gratuity per kilowatt hour for newly installed solar panels by an extra amount.

In August 2007, Bareiß joined a travel group to Baku accompanied by lobbyist Otto Hauser, and again in 2010. In June 2012 Bareiß, along with Eduard Lintner, was received by several Azerbaijani ministers.

A business manager by profession, Bareiß has been a directly elected member of the Bundestag since the 2005 elections. In his first term between 2005 and 2009, he was a full member of the Committee on the Affairs of the European Union as well as of the Committee on Labor and Social Affairs. In that capacity, he served as his parliamentary group's rapporteur on Transatlantic relations. Since the 2009 elections, he has been serving on the Committee on Economic Affairs and Energy.

Thomas Bareiß (born 15 February 1975) is a German politician of the Christian Democratic Union (CDU) who has been serving as a member of the German Bundestag since 2005. From 2018 to 2021, he held the position of Parliamentary State Secretary at the Federal Ministry of Economic Affairs and Energy in Chancellor Angela Merkel's cabinet.
